Lyophilisation vials are normally washed and sterilised prior to processing and filling, which requires the use of cleanrooms, washing machines and sterilisation tunnels — depending on the level of containment needed — to perform these tasks. However, to improve efficiency and to reduce time and costs, pre-washed and sterilised ready-to-use packaging materials may offer a solution and improve the overall process. Johannes Selch of ALUS, GEA, in collaboration with Gregor Deutschle of SCHOTT Pharmaceutical Packaging, discusses nested vials for improved lyophilisation efficiency.
